Typo in "Quickstart" section in readme.

[rajeshyogeshwar]

In the quickstart section, the desired signature url is as follows

/domain/ <- Domains list
/domain/{pk}/ <- One domain, from {pk}
/domain/{domain_pk}/nameservers/ <- Nameservers of domain from {domain_pk}
/domain/{domain_pk}/nameservers/{pk} <- Specific nameserver from {pk}, of domain from {domain_pk}

and just below that in how to do it example we have a line,
domains_router = routers.NestedSimpleRouter(router, r'domains', lookup='domain')

Given that it's one example, the urls should have been

/domains/ <- Domains list
/domains/{pk}/ <- One domain, from {pk}
/domains/{domain_pk}/nameservers/ <- Nameservers of domain from {domain_pk}
/domains/{domain_pk}/nameservers/{pk} <- Specific nameserver from {pk}, of domain from {domain_pk}
